2 Claims. (Cl. 101-375) The present invention relates generally to aprinting device, but more particularly to a novel and improved rotarytype printing device which has special adaptations for use in connectionwith the rapid price printing of packages, cans, cartons, bags, allsorts of containers and the like so as to expedite the printing of theprice on a variety of goods and containers thereof.

One of the primary objects of the present invention is to provide anovel and improved printing device of this type which is simple inconstruction and readily adapted to change from one printing disc toanother printing disc or a plurality of them by a simple manipulation ofthe device.

A further object of the invention is to provide a novel and improvedrotary printing device in the form of a handle havin a rotary shafttherein which is adapted to detachably support thereon one or morerotatable printing discs and having means associated with the handle foractuating the disc to discharge the disc from the rotary shaft.

These and other objects are accomplished by providing a construction andan arrangement of the various parts in the manner hereinafter describedand particularly pointed out in the appended claims.

Referring to the drawings:

Fig. l is a fragmentary top plan view of a case of canned or packagedfoods illustrating the manner in which my improved rotary printer may berapidly applied thereto for printing the price on a plurality ofindividual packages at one time;

Fig. 2 is an end elevational view of the device shown in Fig. 1;

Fig. 3 is a cross-sectional view taken on the line 3-3 in Fig. 2;

Fig. 4 is a fragmentary cross-sectional view showing the manner in whichthe printing discs are removed from the rotary shaft; and

Fig. 5 is a perspective view of one of the printing discs.

In illustrating one form my invention may assume in practice, I haveshown the same as comprising a handle which has a longitudinallyextending bore 11 therein. This bore extends throughout the length ofthe handle. Rotatably mounted in the bore 11 of the handle 10 is a shaft12. The shaft 12 has a peripheral flange 13 adjacent one end of theshaft 12 so as to form an inner or thrust bearing against the handle 10and also as a stop for the printing discs in the manner hereinafterdescribed. The other end of the handle 10 is provided with a cylindricalrecess 14. Seated in the recess 14 is a washer 14' which is secured tothe end of the shaft 12 by a machine screw 15. The threaded portion ofthe screw is mounted in the internally threaded aperture 16 in the endof the shaft 12. The outer end of the shaft 12, as shown at 17, isprovided with a longitudinally extending flattened portion 18 which isadapted to engage a complementary flattened portion 19 of an aperture 20in each of the printing discs 21. These discs are detachably butnon-rotatably mounted on the shaft 12. The

nited States Patent 0 "ice discs 21 are preferably made of metal andhave secured on their peripheries rubber rings 22.

Secured to the peripheries of each of the rubber rings 22 is a rubberprinting tape 23 which carriesthe numerals or printing symbols asindicated at 24. Mounted in a suitable aperture 25 adjacent the outerend of the shaft section 17 is a spring actuated depressable ball 26.The ball 26 is normally pressed outwardly by a prong 27 mounted in, theaperture 25 as clearly shown in Figs. 3 and 4 of the drawings. The ballis so supported in the aperture that it is permitted to only partiallyproject from the flat surface 19 of the shaft portion 17. Obviously theprojecting ball will frictionally resist accidental removal of the discsfrom the shaft and at the same time will permit the discs to be removedtherefrom when sufficient pressure is used for that purpose.

In order to facilitate the removal of the discs from the shaft, I haveprovided a longitudinally movable sleeve 28 which is slidably mounted ona reduced diameter or recessed section 29 on the inner end of the handle10. This sleeve 28, when in its normal position as shown in Fig. 3, hasone end thereof adapted to engage a shoulder 30 formed on the handle 10.Extending longitudinally of the sleeve 28 is a slot 31. Extendingthrough the slot 31 and secured adjacent the inner end of the handle 10is a headed pin 32 which forms a guide as well as stop for limiting theoutward or relative movement of the sleeve 28 with respect to the handle10 in the operation of removing the discs 21 from the shaft portion 17.In other words, in order to remove the printing discs from the shaftportion 17, the sleeve 28 is actuated or pushed outwardly from theposition shown in Fig. 3 to the position shown in Fig. 4 of the drawingsto thereby depress the ball 26 and disconnect the discs from the shaft.This arrangement is obviously for the purpose of preventing the handsfrom becoming smeared with ink in the operation of removing or changingthe discs.

In Fig. 1 of the drawings, I have shown a fragmentary portion of a caseof canned or packaged goods which includes an outer casing or container33 and circular packages or cans 34 mounted therein. It will be obviousthat when the printing discs are properly inked on an inking pad, thehandle or printing device may be run rapidly across the tops of thepackages or cans 34 so as to imprint a continuous succession of pricenumerals on each of the individual cans or packages. This succession ofrepeated numerals on each package or can insures a clearer imprint whichcan be immediately located by the checking clerk.

While in the above specification I have described one embodiment whichmy invention may assume in practice, it will, of course, be understoodthat the same is capable of modification and that modification may bemade without departing from the spirit and scope of the invention asexpressed in the following claims.

What I claim as my invention and desire to secure by Letters Patent is:

1. A rotary printing device comprising a handle, a shaft journaled insaid handle and protruding from one end thereof, a detachable printingdisc detachably secured to said shaft, spring actuated means mounted onsaid shaft and engageable with said disc for resisting the removal ofsaid disc from said shaft, and means mounted on said handle andengageable with said disc for removing said disc off the end of saidshaft over said spring means.

2. A rotary printing device for successively printing a plurality ofmerchandise, goods or packages comprising a handle, a shaft journallysupported by said handle, one or more printing discs removably securedto said shaft, a spring pressed ball mounted on one end of said shaftand movable into the path of said disc for resisting the removal or saiddisc, and a sleeve longitudinally movable Refenences Cited the. file Ofthi patent UNITED STATES PATENTS 1,445,627 Kissner et a1.
